PeaZip can
spare disk usage (and substantially improve download/upload speed of
backup copies)
creating backup with use
of strong compression algorithms - as a
role of thumb ZIP / GZip compression can save 50% of disk space applied
on mixed-type input data, Bzip2 and 7Z compression provides better
result at cost of more computing power/time.<br>
Deduplication of non-unique files before kackup jobs prevents excessive
disk space usage for storing redundant data.<br>

            <div style="text-align: justify;"> </div>
            <a name="protect_from_data_loss"></a>A very common way to
programmatically have the data secured by a backup
copy is to schedule this process
when the machine is not planned to be
used intensively (i.e. during night hours).<br>
While specific backup programs can feature built-in advanced functions
for backup &amp; restore operations (i.e. differential backup which is
the process of
saving only a copy of the data actually changed since the last backup
task, or low level disk copy routines to physically clone the hard
disk, more common in software specifically meant for cloning disk
images), one of the advantages of PeaZip is being able to
save file compression operations (as well as file conversion or
extraction operations) from GUI to a script file, in order to re-use
the job definition with any system scheduler, or in third party
programs
and scripts: Add &gt; Console &gt; Save job definition creates a plain
text file
containing the task definition, saved by default in a "Scripts"
subfolder in PeaZip's configuration path, which is unique for each user.<br>

for 7Z files, which also provides (optional) encryption
of table of content of the archive, allowing to keep private also the

password or passphrase is provided - avoiding unwanted leak of

multiple <a href="verify-checksum-hash.html">error

checksums to cryptographically strong
hashes: Adler32, CRC family
(CRC16/24/32/64),

corruption or forgery that may occour if the data comes from
unreliable sources, such as disks undergoing failures or unreliable
network connections.<br>
File check may be automatic, as most archiving format supported by
PeaZip stores advanced error detection information in the archive, or
manual.<br>
In example, if the hash of a downloaded file is published by the author
of the file it is possible to re-calculate it with PeaZip to assure it
matches with original one, meaning the originally intended file was
actually downloaded without errors and without being replaced or
corrupted by an attacker in any stage of the communication.<br>

Android or ChromeOS, and Apple
MacOSX / iOS.<br>
PeaZip file explorer shows available shared directories in the
navigation area (on
the left) of file browser, so shared files are quickly accessible - and
also in compression/conversion and extraction screens, to allow quick
selecting sync folders as target for archiving and extraction
tasks.<br>
This is especially useful when sharing archive files with mobile or
ultramobile devices and gadgets not
able to run a full featured file archiver (i.e. because some archive

enough powerful for convenient use of strongest compression algorithms,
